SERETIDE Plus Tiotropium Versus Individual Components
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This study was designed to evaluate the effects on lung function of a combination of SERETIDE 50/500mcg twice daily plus tiotropium bromide 18mcg once daily compared with the individual treatments (tiotropium bromide 18mcg once daily alone and SERETIDE 50/500mcg twice daily alone) in subjects with COPD. The study will utilise a three-way cross-over design with a 2-week wash-out period between each 2-week consecutive treatment period.
